To all whom 'it 'may concern:

Be it known that we, ELrn Lacos'rn and citizens of-the Re public of France, residing at Paris, Depertinent of the Seine, have invented certain nenT and useful Im provenients in Propelling. Mechanism for Motor-Vehicles, of which the following is a specification. l 1

This invention refers to a complete propelling mechanism for motor vehicles, offer; ing considerable economy and facility in its manufacture, putting together,'taking to. pieces and transporting. The taking to pieces and assembling is effectedwithr very little trouble and Without any adjusting-at the saine time the device 'assures perfect alineinent of the various parts and forms a ein. Furthermore, according to this arrangement, the moving parts are protected and their lubrication is assured, the various parts having toisupport This invention'consists in arranging the various propelling mechanisms of 'motor vehicles a series .of casiIl-gs each forming a each group po'essing. all its controlling parts. The casings of these various groups are adjusted coaxially with each other by means of ton e and groove joints formed on the ends 0. Athe .casings and thus are'connected up to form .a rigid block. The coupnp of the various casings ,with each other also couples up the mechanisms conth'e parts of one group penetrating into the corresponding ,parts of the adjoining group, so as to forma line of transmission shafts coaxial with the tongue and groove joints of the casings and consequently in the theoretical prolongation of each other.

One of the chief characteristics of this invention consists in forming as above escribed a complete automotor mechanism from 'the back Wheels to the starting crank, the mechanism being provided with all its controlling parts, such as pedals, ylevers and the like and terminating in front by a h ollovvl sphericalportion, b means of which the propelling effort of the driving wheels is transmitted to thebody ofthe vehicle through an elastic spherical .hearing pro.-

vided on the front .of the body of the ve- Specification of Letters Patent.

'hiele. Thus as the automotor mechanism contains all its controlling parts, ,it is pos sible to connect this mechanism almost instantaneonsly to the body of the vehicle, just as a horse is harnessed up, that is to say by' engaging the 4front spherical or hall portion in the bearing provided on the front crossbarof the body of the vehicle and by bolting the springs of the body at the' bacli on to the supports or shoulder of the ,bach axle-tree. Vhis arrangement can be adapted to all kinds of bodies, Whatever may he their shape or length 'it only being necessary to vary the length of the connecting casing and of the transmission shaft.

-Referring to the accompanying drawings :-l*`ignr e l shows in elevation the ailtomotor propelling mechanism. lig. 2 is a plan View of the automotor'mechanisim different groups ofmcchanism being shown in section and separated from each other.

the

Fig. 3 is a cross-section on an enlarged scale of the connecting up mechanism D. Fig. 4 is a section on an enlarged sca-leef the front ball joint, showing Afor the sake of example an arrangement rendering the bearing elastic ina longitudinal direction.

As may be seen from the drawings 4the back axle is formed'bya easing A A, pro vided with spring and brake supports l and the hubs with their Wheels f2. The differ en tial 3 and its driving bevel- Wheel l is situated 'inside this casing. The levers 6 with the connecting bar 7 for actuating the hub brakes are arranged on the' shafts 5 outside the casing. A. This casing terminates'in a circular projecting tongue a. The grooves b, b are formed in the ends of thel connecting casing B, the transmission shaft 8 passing vthrough Athe `casing coaxially with the cirl cula-r grooves 2'), Zi This shaft -8 is terminated at one end by the pinion 9 'which meshes with the driving head l() which can engage in a corresponding recess of the brake pulley of the change-speed gear. The change-speed .gear consists of a `casing C- provided at either end vvith projecting circular tongues c, c which exactly engage in the ,corresponding grooves of the adjoining easings B and The main shaft l1 of the change-speed gear turns in the interior of this casing coaxially With the tongues c, o.

l This'shaft llterminaltes at its back portion bevel Wheel 4, and

- changespeed gear wheels, the penetration casing C' also supports-- the lever 15 conTA trolling the brakes of the back wheels, as well as the change-speed lever 1'6. This lever 16 penetratesl directly to the interior of the change-speed gear so as to control the gear wheels without the use of any intermediary part.. It Ashould be remarked that thelever 16 is connected'to the casing C by a ball and socket joint, so that this lever can pivot both in a lateral as well as in a longitudinal direction, so as to control the two into the casing being rendered dust-tight by the ball portion.

The connecting up or clutch mechanism consists of a casing- D terminating at one end by a groove (Z, and at the other end by .a

tongue cl coaxially with each other. The connecting-.up cone carried by the shaft 11 of the change-speed gear turns at the interior of this casing D coaxially with these tongues and grooves; the square head 14 of the shaft 11, when connecting up the casings, engaging a square recess formed in the coniiecting-up cone. The casing D carries the pedal 17 directly controlling the connectingup cone by means of the fork 18. The casing Dalso` carries the brake pedal 19 which, by means of the levers 20, 21 arranged at .the interior, controls thel brake of the changespeed gear situated in the pulley 12, the holes through which the shafts of the pedals 17 and 19 penetrate into the casing are rendered dust-tight.

The mechanism of the motor -is situated in a casin E and its". .,crank 22 turns coaxially wit .the grooves e, e in the ends of this casin This casing also carries the carbureter, t e magneto, the lubricating pipes, the fan, not shown,'a1l controlled directly by this engine.

The female cone 23 of the connecting up mechanism is centered on a' circular tongue 24 of the y-wheel and the crank is terminated at -the other end by a prolongation provided with al starting pin 25.

The starting mechanism consists of a casing F at the back of which-.is formed a tongue. f which engages in the groove-:of the motor-casingE'. The casing F terminates in front in a ball portion 2 5 coaxial with the tongue f. The `starting shaft, terminated in front by the crank 26 and at the back by the clutch 27, can turn in the interior of this'casing F. Finally the casing Gr of the bearing in two ieces with spherical boring 29 can be fitte i to the front crossbar 28 of any vehicle body. The ball portion of the casing F can turn freely in all directions in the interior of this bearing 29 without any eifort and coaxially with allthe mechanism, and can transmit Ato the body of the .vehicle the thrust exerted by the back wheels through all tliecasings.

In'order to check the shocks or vibrations r resulting from the back Wheels traveling.

overuneven ground, compensating springs 30 are provided on each side of the bearing and permit the bearing to move longitudi-A nallyin its casing G, in accordance with the thrust of the mechanism.

It will be seen from what has been stated above that each group is an independent'A whole provided with its controlling parts andthat they can be directly connected-up coaXially with each other and held together by bolts not shown. In this manneran` absolutely complete automotor propelling -mechanisin, altogether independent offthebody of the vehicle for which it is intended,` is obtained.

By introducing the ball joint into the socket bearin fitted to the front cross-bar of the body o the vehicle and by fixing the back springs on to the supports of the back acked separately and the mounting is efected by simply placing these groups together without any adjusting being neces` sary and only necessitates a few hours work. 1t is of course understood that the body of the vehicle rests by means of springs on any front axle-tree whatsoever' and that it is provided with the steering gear for controlling the same.

What we claim and desire to secure by Letters Patent is,-

l. A motormechanism for vehicles composed of a series of separate independent casings each containing its own mechanism, the ends of the casings being provided at the circumferencewith tongue and 'groove joints, and having j ournaled in their ends coaxially with the tongue and groove a series of separate, independent-driving shaft units adapted to engage automatically at their ends in driving relation, the casings when bolted together at their ends forming a continuous rigid straight line connectionV the back -circumferences with tongue and groove' joints, and having journaled in their ends, co-aXially with the tongue and groove, a .series of independent driving shaftl units adapted to engage automatically at their ends in driving relation, the casings when bolted together, forming a' continuous rigid axle-tree, a motor vehicle ready for immediate service is obtained in a few minutes. 1 For economical transport each group can be iio' @might Ene rmectin'betwn the crank- In Witness whereof We have hereunio sei;l
